Journal ArticleDOI
Are AGN broad emission lines formed by discrete clouds? Analysis of Keck high‐resolution spectroscopy of NGC 4151
TL;DR: In this article, the authors apply cross-correlation analysis to a high-resolution Keck spectrum of the galaxy NGC 4151 to search for a direct signature of discrete clouds in the broad-line region (BLR) of the Seyfert galaxy.
Journal ArticleDOI
The External Shear Acting on Gravitational Lens B 1422+231
TL;DR: In this paper, spectroscopy and near-infrared and optical photometry of galaxies in the field of the quadruple lens system B 1422+231 was presented, showing that the primary lens and five nearby galaxies belong to a compact group at z = 0.338.
Journal ArticleDOI
